As a professional trader i view crypto currency (for the most part) as a slow walk through a penny casino.

Now am i saying investing in crypto is akin to gambling?
I've been involved with BitCoin since Mt Gox....so i've seen it stir up noise...then go dead...its not a market for the faint of heart.
It is a tough question,id say it depends on a few things... the project(or product at hand)& the team behind it....and what problem does it solve?
But that's me.

I study/research my investments (It's what i do for a living 20+ years now)
(check out their GitHub for example/whitepaper/website)
DON'T base your investments on Telegram groups or YouTube videos.

I'd honestly say...70-80% of the coins you see in the top 200...won't exist in 2 years.
Not because of scams/bad PR...just no product/prototype/nada

My favorite example is TRIG.
No prototype (on the original roadmap it was supposed to have one by late Jan)
No HQ
New Roadmap is 2 months long (Still trying to 'develop' prototype)

To me...it sounds like a pie in the sky project....and will never come to fruition.

Now the positive example...let's use STEEM
Has a working blockchain
Has a purpose & multiple working parts (DTUBE etc)
Solves the problem ,creates a decentralized social media platform that isn't ad run.
Not only can you create content but be compensated for it.

There are a ton of overhyped projects ,but this isn't the place nor time to call them out.
Id say for you @greeker02 ,think of projects you look at it and say "Now this is a legitimate technology"
Research the company & team.

If all check out...you got yourself a keeper.
Might it fail?
Sure
This is a speculators market....a tweet cuts Neo's price down by 25%
A tweet.

So if your risk tolerance isn't high...this won't suit you.

This is a long term investment...meaning years not months.

Hope this helps.
